Best Doctor For Urinary Tract Infection Treatment in Mumbai The term acute complicated urinary tract infection (UTI) refers to UTI with features such as fever with chills or rigors, altered mental status or flank pain. Relevant uropathogens include primarily Escherichia coli and other gram negative bacilli. Risk factors for resistant organisms include recent broad – spectrum antimicrobial use, hospital admission and any urologic procedures. Acute complicated UTI should be suspected in patients with dysuria, urinary frequency or urgency, or suprapubic pain who also have fever, chills, flank pain, or otherwise appear clinically ill. In men pelvic or perineal pain accompanying urinary symptoms suggests prostatitis. For patients with suspected acute complicated UTI, we send urine for both urinalysis and culture. Imaging is generally reserved for those who are severely ill, have suspected urinary tract obstruction, have persistent symptoms despite 48 to 72 hours of appropriate antimicrobial therapy, or have recurrent symptoms. The diagnosis of acute complicated UTI is made in patients who have consistent clinical findings as well as pus and bacteria in urine. The specialist doctors should be approached at the earliest onset of symptoms and the appropriate investigations advised, should be done.
